  • Dr. Gombera had a great bedside manner, explained things thoroughly, and made my daughter feel comfortable and relaxed. Very nice guy. He took the time to explain things in a way that was easy to understand. We would absolutely treat with him again and recommend him.

  • This was a follow up visit for a possible potential problem, but upon examination and x-rays turned out to be nothing to be concerned about and Dr. Caronis was excellent about re-assuring us of that fact. Dr. Caronis always takes his time with us always explaining everything to us and his whole manner in all ways is just very pleasing to be around. We have high respect and every confidence in him!

  • Dr. Caronis has been wonderful. I was injured out of town and he responded immediately to my call, saw me first thing in the morning in the hospital. He reviewed my MRI the same day and returned to see me before discharging. He was responsive, compassionate and efficient in addressing my problem.
